Abstract: In gauge theories in the limit of a large number ${N}_{c}$ of colors baryons are usually described as heavy solitonic objects with mass of order ${N}_{c}$. We discuss an alternative large ${N}_{c}$ description both directly in the field theory as well as using holography. In this alternative large ${N}_{c}$ limit at least some of the baryons behave like mesons, that is they stay light even at large ${N}_{c}$ and their interactions vanish in that limit. For ${N}_{c}=3$ these alternative large ${N}_{c}$ baryons are equivalent to the standard baryons. In the holographic description it is manifest that the Regge slopes of mesons and alternative baryons are degenerate.
